Graham 16-Jan-2010 [1603] | sounds like grandiose ideation ! :) |
Maxim 16-Jan-2010 [1604x4] | no its how every other platform does it. |
using tools like SWIG. | |
I want to do it using REBOL end-to-end. | |
and since the C analyser has a programable emitter, you will be able to customize what it does. | |
Graham 16-Jan-2010 [1608] | What's the ETA for this? Knowing that you start university this week ... |
Maxim 16-Jan-2010 [1609x2] | honestly I don't know, but its a funded project overall, so it is my current job. which means it will happen for sure. I would love to have some usefull OpenGL stuff working in february. |
one reason I'm doing Sea (the C converter) is that for each new improvement of extensions, we will be able to update our tools with a single rebuild of the extension. for large libs this is going to be a big deal. | |
Graham 16-Jan-2010 [1611] | is the funding contingent on delivery ? :) |
Maxim 16-Jan-2010 [1612] | well, usually, you get paid to get things done. but this is an ongoing project. It also has other libraries I must import which I can't talk about right now, but which might be very interesting for the community. |
Graham 17-Jan-2010 [1613x3] | As I said above I don't use imap, and am not familiar with the protocol. All this does is login using auth=login and grabs the first mail in the Inbox http://rebol.wik.is/Rebol3/Schemes/Imap4 |
I don't parse any of the message flags etc. | |
Ok, what do we need for imap? ( although I suspect doing all these email schemes is a waste of time without ssl ) ... | |
Andreas 17-Jan-2010 [1616] | for developing, stunnel will help with immediate ssl issues |
Maxim 17-Jan-2010 [1617] | ssl AFAIK is under the protocol, so even with an SSL module, the schema should not really change. |
Graham 17-Jan-2010 [1618x3] | stunnel adds transparency ... I guess |
anyone got a how to on using stunnel ? | |
The r2 imap protocol is pretty basic ... so I don't see that we need do more than that ....except perhaps allow users to pass custom commands to the server. | |
Andreas 17-Jan-2010 [1621] | stunnel -cf -P '' -d sourceport -r targethost:targetport |
Graham 17-Jan-2010 [1622] | thanks |
Andreas 17-Jan-2010 [1623x3] | -c is for client mode, i.e. so that stunnel will connect to a server -f is so that stunnel stays in the foreground (and you see debug output) -P '' is to avoid creating a pid file (dunno if that is necessary on win32 stunnels) -d sourceport tells stunnel to listen on sourceport -r targethost:targetport to forward data to this target |
re imap: i don't think that much of anything is necessary for imap atm. once i'm satisfied with the pop protocol, adapting it to imap will be quick and easy | |
the more interesting questions would be about a satisfying user interface. mostly how to wrap imap folders nicely in something that feels natural in rebol | |
Graham 17-Jan-2010 [1626] | at present I think you have to specify the folder you want to open in the url for r2 |
Graham 18-Jan-2010 [1627] | Since FTP, andIMAP have folder structures, I propose that we use cd, ls, pwd etc for those schemes that support this. This is no different to the lookup that is done by read, write, length? etc |
BrianH 18-Jan-2010 [1628x2] | Won't work without native changes to CHANGE-DIR, which calls the OS change directory function in the host code. In R3 the current directory is real on platforms that have a current directory (i.e. not WinCE), not faked like on R2. |
Such changes to CHANGE-DIR could break R3 rather thoroughly. | |
Graham 18-Jan-2010 [1630x2] | Why? All it does is check the port type first ... |
and if it's not a file!, then check the scheme to see if there is an actor defined. | |
BrianH 18-Jan-2010 [1632] | Um, no, ports aren';t supported at all, just file! types. You can't even use file:// urls. |
Graham 18-Jan-2010 [1633] | well, still can't see that the issue is not insurmountable .. but we can define 'cd, 'pwd, 'ls, 'rm etc to what needs to be done. |
BrianH 18-Jan-2010 [1634x3] | You could redefine the file and dir schemes in the host code to a virtual file system. It would be easier to have the operating system mount the urls to the filesystem, at least on Windows, OS X and *nix. |
The trick is that the file and dir schemes are defined to be relative to the OS current directory, so you can't separate the two. | |
It would break CALL too. | |
Graham 18-Jan-2010 [1637] | cd: func [ d [file! port!] [ either file? d [ change-dir d ][ ; look if supported cd method in actors, and execute it ] ] |
BrianH 18-Jan-2010 [1638] | It doesn't matter, since the only thing about CD that matters is changing PWD, and PWD has to be the OS current directory for R3 to work. However, what "the OS current directory" means is defined in the host code. |
Graham 18-Jan-2010 [1639] | rebol doesn't seem to have a concept of a currernt directory as in windows ... where you can keep a directory for each volume mounted |
BrianH 18-Jan-2010 [1640x3] | You are thinking R2. R3 does have a current directory. |
The only thing about PWD that matters at all is relative filenames, and those are handled by native code, not mezzanine. But most of that native code is in the host since it's platform-specific. | |
Afaik, the R3 current directory is process-specific and is only one, not one per drive. | |
Graham 18-Jan-2010 [1643x3] | http://rebol.wik.is/Rebol3/Schemes/Imap4 Updated to version 0.0.2 Logs into Imap server using cram-md5 if available Switches to inbox gets inbox status for unseen messages Retrieves the first 3 messages |
As Andreas notes, a write to the port inside the awake handler is fine .. but outside the handler, you have to do a wait on the port to do anything. Also i found that without using a timeout value, it doesn't work for me So, I removed the 'read cmdport from write-cmdport function, and put the wait instead in the actor 'read ... | |
with a timeout | |
Graham 19-Jan-2010 [1646x7] | I've got the imap protocol to the point where 1. can authenticate using cram-md5 ( reused r2 code ) 2. can select different mailboxes ( unlike r2 where you have to select at time of opening the port ) 3. length? 4. Pick messages However, I don't like this timeout which is there .. |

using run as admin | |
time to read the manual :( | |
I thought yahoo had free imap service .. but can't find it now :( | |
Nope ... not free. | |
Looks like AIM still has free IMAP ... signing up again! | |
